Paipu kila ERW EN10210 S355J2H kūkulu ʻia

I kēia mau lā iho nei, ua hele mai ka mea kūʻai aku i ka hale hana e kipa iā S355J2paipu i hoʻopaʻa ʻia, i ka huakaʻi holoʻokoʻa, wahi a ke limahana kūʻai aku me ke ahonui.S355J2HHe paipu kila kalapona-manganese kiʻekiʻe ke ʻano o ka paipu kila ERW me ke kūpaʻa maikaʻi loa i ka hopena. Hoʻohana pinepine ʻia kēia mea i nā noi kūkulu e like me nā hale, nā alahaka, nā alaloa, a me nā ʻano papahana kūkulu ʻē aʻe.

Hana ʻia nā paipu kila S355J2H me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe uila (ERW), kahi e pili ana i ka hana ʻana i nā papa kila pālahalaha i loko o nā paipu a laila hoʻoheheʻe i nā humuhumu. ʻO ka hoʻohui kemika o ka paipu kila S355J2H ERW e komo pū me ke kalapona, manganese, silicon, phosphorus, a me ka sulfur, a ʻo ka ikaika hua liʻiliʻi loa he 355 N/mm². Loaʻa i ka paipu nā waiwai mechanical maikaʻi, me ka ikaika tensile kiʻekiʻe loa o 510-680 N/mm². Loaʻa iā ia ka weldability maikaʻi loa a ʻo kona ʻike kalapona haʻahaʻa e kōkua i ka hōʻemi ʻana i ka pilikia o ka hana ʻana o nā māwae i ka wā o ka hoʻoheheʻe ʻana. ʻO kekahi o nā pono nui o ka paipu kila S355J2H ERW ʻo ia kona kūpaʻa kiʻekiʻe. ʻO kēia ka mea e kūpono ai no nā noi kahi e hiki ai i nā paipu ke kau ʻia i nā ukana kaumaha a i ʻole nā ​​​​haʻalulu. Eia kekahi, ʻo ke ʻano like o ka mānoanoa o ka paia paipu a me nā ʻili laumania o loko a me waho e hāʻawi i kona kūpaʻa kūkulu a me ka maʻalahi o ke kau ʻana. S355J2HPaipu kila ERWLoaʻa i nā nui like ʻole a me nā lōʻihi, e lilo ia i koho versatile no nā ʻano hana like ʻole. Hiki ke hoʻohana ʻia e lawe i nā wai, nā kinoea a i ʻole nā ​​​​mea paʻa a, ma muli o kona ikaika kiʻekiʻe, hiki ke hoʻohana ʻia no nā kumu kūkulu. I ka hōʻuluʻulu manaʻo, ʻo ka paipu kila S355J2H ERW kahi koho mea hilinaʻi a paʻa hoʻi no nā ʻano hana kūkulu like ʻole. ʻO kona kūpaʻa kiʻekiʻe i ka hopena, nā waiwai mechanical maikaʻi loa a me ka versatility e kūpono ia no nā ʻano hana like ʻole.
